Step 7: 1. Ensure webbing slot on sling webbing bracket has no sharp edges or burrs. Use a file and/or coarse sandpaper to smooth sharp edges and burrs from webbing slot. 2. Reinstall existing mesh sling seat. Step 8: 1. Remove wooden board (loosen A/C evaporator cover so board can be removed). 2. Identify and drill out the five (center) rivets in the area located above the cross member. Cross member (Reference) Wooden board (Reference) 3. Using a 12.5mm drill bit, drill out ONLY the center hole of the five where the rivets where removed in step 2. 4. Install one (1) 3/8-16 Rivet-Nut Fastener in the 12.5mm hole from step 3. STEP #2 Rev.: A Page 8 of 10
5. Position the adaptor plate on the floor and secure with 3/8-16x2 counter-sink bolt, using the center hole in plate to the rivet-nut installed in step 4. NOTE: the adaptor plate shall be mounted on top of and in line with the B-beam. 6. The remaining four (4) rivet-nuts shall be installed one at a time to make sure that the pre-drilled counter-sink holes on the adaptor plate properly line up. This is to be accomplished by first mounting the plate; drilling ONLY ONE of the holes through the B- beam with a 12.5mm drill bit using the plate as a drill template and then removing the plate to install that rivet-nut. The plate is to be re-installed with a 3/8-16x2 counter-sink bolt in each of the rivet-nut s that have been installed at that time and selecting another of the holes to drill out. This process will be repeated until the remaining four (4) rivetnuts are installed; each time removing and replacing the plate (in any sequence). NOTE: DO NOT DRILL MORE THAN ONE HOLE WITHOUT FIRST REMOVING THE PLATE TO INSTALL A RIVET-NUT. 7. Mark the position of the plate on the vehicle floor so that the markings may be transferred to the wooden board. 8. Place wooden board into position; install a few screws to locate board as required. Transfer markings from vehicle floor to wooden board and remove board accordingly. 9. 10. Cut wooden board and discard center section. Place 7/16 x.363 long spacers (qty 5) over each of the rivet-nuts. 11. Place wooden board into position and screw down board with existing screws. Secure the edge of the wooden board, alongside the adaptor plate where the upper ribbed floor meets the underside of the wooden board, using three (3) self-tapping screws on each side.
